Lighting for Ezra Street

I was thinking about our filming location tomorrow at Ezra Street. I just realized that it was going to be pretty dark at the time which would make it difficult for us to film because we only have a minimal number of batteries for the artificial light. This would mean that we will have to be very efficient with the light in order to save the battery power. One way in which we could do this is by practicing every shot once or twice using ONLY the street lights; this will enable us to make sure that our actual filming with the light will be better and efficient.
I came across this video on YouTube on lighting and found this tutorial very beneficial in preparation for tomorrow.
